Federal prosecutors today charged a Registry of Motor Vehicles employee with conspiracy to defraud the government, alleging that he produced false driver’s licenses while working at the Revere office.

In its case against 24-year-old Alexander Brewer, of Boston, the Department of Justice alleges that from December 2011 to December 2012 he knowingly issued Massachusetts driver’s licenses to people who presented Puerto Rican identifications that did not belong to them.
